Interesting article. There's no doubt that climate is cyclical throughout the solar system and the whole 'global warming' debate has reached hysterical proportions, with 'experts' on both sides presenting compelling evidence both for and against. One thing's for sure though, as a species, we are soiling our nest with waste and pollution and the long term results don't bode well for the future. If not global warming the other impacts are equally alarming. Either way, we do need to clean our act up, before our air is toxic, our crops don't naturally reproduce, our bees die out and delicate ecosystems are destroyed to the point the earth can no longer support us. The current witch hunt seems to be plastic but I'm sure it'll be something else soon.
